CQRNET.

Application filed October 8, 1914.

lb all whom it may concern:

Be it known that 1, CHARLES G. Conn, a citizen of the United States,residing at Elkhart, in the county of Elkhart and State of Indiana, haveinvented certain new and useful Improvements in-Cornets, of which thefollowing is a specification.

The object of my invention is to avoid the short turns found in the windpassage of cornets heretofore used and in so doing,

produce an instrument which plays freer,

better and more satisfactorily in every way and at the same time gives agreater volume Another object of my invention is to place the tuningslide between the valves and rear end of the bell tube and in closeproximity to the thumb of the operator s hand when in playing position,so that the player may tunethe instrument as he plays by turning thethumb screw which is connected to thetuning slide.

In the drawing Figure 1 is a side elevation of a eornet embodying myinvention;

Fig. 2 is a similar view of a side of a cor net opposite to that shownin Fig. l.

The reference numeral 1 designates a mouth pipe and 2 the valves of acernet of any approved construction. 3 designates the bell tube, orbell, the bore of which is of a gradual taper from end to end.

4ris a quiclr-ehange-to-llt slide in the I mouth pipe.

The principal tuning slide, as shown in. the drawings, is positionedbetween the valves and. the inner end of the bell 8, in an upright orperpendicular position. llhat to say, the principal tuning slide isupright or perpendicular to the main longitudinal lines of the cornetwhen the cornet is held in playing position.

The member 5 of the principal tuning slide is shown in the drawings asleading from the first valve casing, but it is, of

course, obviou. that it may lead from either of the valve casings asfound most desirable. This member is deflected downwar lyand thenceupwardly to a vertical or per pendicular position. 6 is another uprightmember of the main tuning slide which is of greater diameter than themember 5 and Specification of Letters Patent.

of a diameter equal to the inner end of the bell pipe. 7 is theslidingmember of the main tuning slide, one leg of which is of diameterequal to the diameter of the member 5 while the other end is of agreater diameter and equal to the diameter of the member 6, from whichit will be seen that the wind passage, commencing atthe top of themember 5 is of increasing diameter through the slide 7, member 6 and thebell pipe 5 i ich results in the instrument playing freer, better andmore'satisiactery and which enables me to get a greater/volume of toneout of the instrument.

I have shown in the drawing a bracket 8 secured between the members 5and 6 of the tuning slide in which bracket is revolubly mounted a thumbnut provided with interior screw threads while 1' have secured a stem 10to the slide member '2', one end of ing freer and giving bettersatisfaction and I a greater volume of tone. In the old style of cornet,it was necessary to remove the cornet from the players' lips in order totune it, it often requiring several trials before the desired tone couldbe attained, whereas in my invention the player can tune his instrumentwhile he is playing, by simply moving his thumb over the knurled thumbscrew 9, thereby not losing single note of the composition. I

I claim l. A cornet having a tuning slide in the form of an open-ended,vertically arranged loop, positioned between the first valve casing andthe mouth piece, said loop comprising part of the tube connecting saidcasing and the bell tube; a thumb nut held against axial movement and acoacting screw held against rotation. positioned within the aforesaidloop for. adjustingsaid tuning slide.
